Locking device
Abstract
A conventional barrel-type combination lock receives a lock
element extending from a safety pin housing. The safety pin housing
pivotally receives a pin that pivots between an open position and a
closed position relative to the safety pin housing, and the lock
element of the barrel-type combination lock is moved to the locked
position, the end of the pin is positioned within a pin receiving
recess on the barrel-type combination lock so that the pin is
locked in the closed position. A conventional chain formed from a
series of interlocking links is utilized with the lockable safety
pin to enable small articles to be locked to fixed objects. When
the chain is not in use, it is stored within a cylindrical chain
storage container that is threadedly received upon the end of the
barrel-type combination lock. With the pin closed and the
combination lock in the locked position, and with the chain
positioned within the storage container theaded onto the lock, the
personal locking device is of a size convenient for carrying in a
purse or pocket of the potential user.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an apparatus for locking personal items
to secure them from theft, and more particularly to a locking
safety pin-like unit in combination with a chain for locking
personal articles to a fixed object to prevent theft.
2. Description of the Prior Art
Many efforts have been made to provide locking devices with which
to secure small articles of personal property such as purses,
briefcases, coats, skis, and other personal items where
circumstances demand that they be left unattended for a period of
time. A common locking device of this type is a chain and padlock
used to prevent the theft of an unattended bicycle.
A known device for securing smaller personal articles is disclosed
in the U.S. Pat. No. 3,611,760 and consists of a combination lock
and a cable which may be utilized to secure a briefcase to a fixed
object. Combination cable locks are well known and the following
U.S. Pat. Nos. are representative of this type of lock: 1,222,920;
1,267,894; 1,472,206; 1,627,462; 3,906,758; 4,064,715; 4,398,403;
4,543,806; and 4,597,273. Earlier known devices utilizing
combination chains and lockable pins are disclosed in U.S. Pat.
Nos. 200,990; 599,765, and 1,632,338.
While locking devices are well known, none of the known devices
permit small articles to be locked universally to fixed objects. In
most cases the construction of the known locks limits their use to
specific applications and are generally cumbersome. Therefore,
there is need for a locking device that may be utilized to
universally attach small articles to a fixed or stationary
object.
SUMMARY OF THE INVENTION
In accordance with the present invention, there is provided a
locking device that includes a lock having a housing with a pin
receiving recess formed therein. A lock element is slidably
received within the lock housing. The lock element is movable
relative to the lock housing between a locked position and an
unlocked position. A pin housing is connected to the lock element.
A pin is pivotally retained on the pin housing for movement between
an open position and a closed position. The lock element is movable
relative to the lock housing when the pin is in an open position.
The lock element is fixed relative to the lock housing in the
locked position when the pin is received within the pin receiving
recess to lock the pin in a closed position. A length of chain is
provided for wrapping around a fixed object. The chain is formed of
a plurality of interconnecting links. A slide member has a bore
therethrough. The chain extends through the bore and from the slide
member to form a loop extending from the slide member. The pin in
the closed position extends through the slide member to secure the
slide member to the pin housing.
Further in accordance with the present invention, there is provided
a locking device that includes a lock housing having a pin
receiving recess formed in one end thereof. A lock element is
slidably received within the lock housing and is movable relative
to the lock housing between a locked position and an unlocked
position. A pin housing is connected to the lock element and spaced
from the lock housing. A pin is carried by the pin housing for
movement between an open position and a closed position. The lock
element together with the pin housing is movable relative to the
lock housing for positioning of the pin in the pin receiving recess
to secure the lock housing in the locked position and the pin in a
closed position. A length of chain formed of a plurality of
interlocking links is provided. A chain choke has a bore
therethrough for receiving the chain. One end of the chain is
secured to the chain choke and extends therefrom through the bore
to form a loop of a preselected size extending from the chain
choke. Means extending through the chain choke engages the chain in
the bore to prevent movement of the chain in the bore to maintain
the size of the loop extending from the chain choke.
Additionally, in accordance with the present invention, there is
provided a method for locking a lightweight portable object to a
structure that includes the steps of securing a length of chain in
a loop around the structure. A slide member is advanced along the
length of chain to close the loop to a preselected size around the
structure. A lockable safety pin passes through an aperture in the
object. The lockable safety pin passes through the slide member.
The lockable safety pin passes through at least one link of the
chain. Thereafter the lockable safety pin is locked to prevent
slidable movement of the slide member on the chain to maintain the
preselected size of the loop around the structure.
Accordingly, the principal object of the present invention is to
provide a convenient, self-contained personal locking device for
securing small articles to fixed objects.
Another object of the present invention is to provide a personal
locking device which can be easily carried in a pocket or purse and
used in a versatile manner to secure in a locked position a variety
of personal objects to prevent theft or unauthorized use of the
object.
A further object of the present invention is to provide a personal
locking device that includes a pivotal pin movable into and out of
a locked position and secured in a locked position by a barrel
combination lock where a choke is utilized with a chain connected
to the pin in a locked position to securely attach a chain to an
object to prevent theft or unauthorized use of the object.
A further object of the present invention is to provide a pivotal
pin that is movable into and out of a locked position in a barrel
combination lock and associated with a combination chain and choke
for versatile use in closing in a locked position an object that is
capable of being opened and closed or securing a portable object to
a fixed object to prevent theft.
These and other objects of the present invention will be more
completely disclosed and described in the following specification,
the accompanying drawings, and the appended claims.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the drawings and particularly to FIGS. 1-3, there is
illustrated a personal locking device generally designated by the
numeral 10 having a barrel-type combination lock 12 which
corresponds to the combination lock disclosed in copending U.S.
application Ser. No. 874,220 entitled "Personal Locking Device".
Known barrel-type combination locks are also disclosed in U.S. Pat.
Nos. 1,222,920; 1,267,894; 1,472,206; and 1,627,462.
In conventional fashion, the lock 12 has a barrel 14 upon which are
received a plurality of tumbler rings or wheels 16. As well known
the tumbler wheels 16 have internal recesses (not shown) so that
when the recesses are aligned, the lock 12 is in an open position.
When the recesses are not aligned, the lock 12 is in a locked
position in a manner well known in the art. The tumbler wheels 16
have numerals (not shown) around the circumference of each wheel 16
so that when the recesses are aligned the numerical combination of
the lock 12 appears in alignment on adjacent tumbler wheels 16 in
conventional fashion. Even through the above described combination
lock 16 is described for use with the present invention, it should
be understood that other types of locks, such as conventional key
locks, are equally adaptable to the present invention.
The barrel 14 includes an enlarged end portion 18 and a reduced end
portion 20. A pin receiving recess 22 extends through the enlarged
end portion 18. Extending between the enlarged end portions 18 and
20 is an arbor portion 24 which includes a longitudinal bore 26
that extends downwardly from the top of the arbor 24. The bore 26
extends from the pin receiving recess 22 to the reduced end portion
20.
A lock element 28 is positioned in the bore 26 of the barrel 14 and
moves in sliding, axial relation to the barrel 14 between the
locked position shown in FIG. 1 and the unlocked position shown in
FIG. 2. Again, in conventional fashion, when the tumbler wheels 16
are positioned so that the lock 12 is in the open position, the
lock element 28 is freely slidable in the barrel bore 26 from the
position shown in FIG. 1 to the position shown in FIG. 2.
The lock element 28, as shown in greater detail in FIG. 9, includes
a longitudinally extending slot 30 for receiving a key 32. The lock
element 28 extends into the arbor bore 26 with the slot 30
vertically aligned with the opening through the arbor 24 which
communicates with the bore 26. The key 32 extends down through the
opening in the arbor portion 24 and is received within the lock
element slot 30. The key 32 includes a plurality of spaced apart
recesses 34. In order to lock the combination lock 12, the lock
element 28 is moved to the position shown in FIG. 1. Then the
tumbler wheels 16 are rotated. In the locked condition, the tumbler
wheels 16 enter the key recesses 34 and prevent the lock element 32
from moving.
The lock element 28 includes at one end, as shown in FIG. 9, an
internally threaded bore 36 for receiving the threaded end 38 of a
stop member 40. As shown in FIGS. 1 and 2, the stop member 40 is
movable toward and away from the reduced end portion 20 of the
barrel 14. The stop member 40 prevents the lock elements 28 from
being completely withdrawn from the barrel 14. Also as shown in
FIGS. 1 and 2, the tumbler wheels 16 are maintained axially fixed
on the arbor portion 24 of the barrel 14 by an external snap ring
42 which is received within a circumferential groove 44 separating
the reduced end portion 20 from the arbor portion 24 of the barrel
14.
Affixed to the opposite end of the lock element 28 is a safety pin
housing 46 which is of generally cylindrical shape and has a recess
48 formed therein. As shown in FIG. 7 and 8, the safety pin housing
46 includes an opening 50 for receiving the enlarged end of the
lock element 28. The lock element 28 includes a transverse boer 52
which when aligned with a transverse bore 54 in the pin housing 46
receives a pin 56 for securing the lock element 28 to the pin
housing 46.
The safety pin housing 46 also includes a groove 58 formed to
receive the pivoted end of a pin 60. The pin 60 is movably retained
on the housing 46 by pivotally connecting the pin 60 to the housing
46 by a pivot 62 retained on the outer end of the housing 46. The
housing 46 also has a pin receiving groove 64 to receive the free
end of pin 60 when the pin 60 is in the closed position in the
barrel pin receiving recess 22, as shown in FIGS. 1 and 7.
Referring to FIGS. 1 and 7, when the pin 60 is closed the free end
of the pin 60 fits into the pin receiving groove 64 of the housing
46. Also, a portion of the pin protrudes beyond the safety pin
housing 46 and into the pin receiving recess 22 of barrel 14. In
this position of the pin 60 the lock element 28 is in the locked
position (FIGS. 1 and 7). Thus the pin 60 is locked in a closed
position and may not be opened. When the lock element 28 is moved
to the open position (FIGS. 2 and 8), the end of the pin 60 is
withdrawn from the pin receiving recess 22 and may be pivoted about
pivot 62 to the open position.
A cylindrical chain storage container 66 is received on the end of
the barrel 14 opposite from the safety pin housing 46. The storage
container 66 is connected to the barrel 14 by one or more rivets 68
extending transversely through the body of the container 66 and
into engagement with the body of the barrel 14. The rivet 68 in the
barrel 14 does not obstruct movement of the lock element 28 in the
barrel bore 26. Preferably, the pins are so materially constructed
that in the event an attempt is made to break open the locking
device, the storage container 66 will snap off from the barrel 14,
leaving the combination lock 12 undamaged and the locking device
maintained in the locked position. The cylindrical chain storage
container 64 is preferably formed of metal or a rigid plastic and
similarly the other components are formed of metal or a rigid
plastic.
A chain 70 is provided for use as part of the personal locking
device 10. When the locking device 10 is not in use, the chain 70
is stored within the storage container 64 as shown in FIG. 1. The
chain 70 is formed from a plurality of individual interlocking
links 72 in conventional fashion. In one embodiment (not shown) the
chain 70 is a single continuous loop as illustrated in the above
referenced copending application Ser. No. 874,220. In the
embodiment shown in FIG. 3, a length of the chain 70 is provided
with a first end portion 74 connected by a screw 76 to a knurled
cap 78. The cap 78 is provided with an externally threaded portion
80 adapted to threadedly engage the internal threads 82 with in the
outer end of the storage container 66. When the chain 70 is not in
use, it is retained within the container 66 by threading the cap 78
onto the end of the container 66 as shown in FIG. 1.
The chain 70 includes a second end portion 84 which is connected by
a screw 86 to a choke or slide member 88. Preferably, the choke 88
is cylindrical in diameter to facilitate retention and ease of
movement into and out of the storage container 66, but it should be
understood that the choke 88 may be of any desired configuration
that will permit it to be inserted and removed from the storage
container 66. The choke 88, as shown in FIGS. 3, 8 and 9 includes a
longitudinal bore 90 which intersects with a transverse bore
92.
The chain 70 extends from its connection at end portion 84 from the
choke 88 and through the longitudinal bore 90. With this
arrangement connection of the chain 70 at one end to the choke 88
and extension of the chain through the choke bore 90 forms a loop
94 that extends from the choke 88. Accordingly, the size of the
loop 94 is adjustable by pulling the chain in either direction
through the bore 90. When the locking device 10 is in a locked
position and the chain 70 is stored within the storage container
66, as shown in FIG. 1, the entire locking device 10 has an overall
length of approximately seven inches and has a diameter of
approximately one inch. It is lightweight and may be readily
carried in the purse or pocket of the user until the device is
needed.
In the locked position, as shown in FIG. 1, the locking device 10
can be used without the chain 70 or the choke 88. When it is
desired to use the choke with the locking device 10, the device 10
is unlocked, as shown in FIG. 2, to permit the pin 60 to be pivoted
out of the pin receiving groove 64. The choke 88 is then positioned
on the pin 60 by extending the pin 60 through the choke transverse
bore 92. This arrangement is also shown in FIG. 7 where the choke
88 is positioned on the pin 60 in a closed position. In FIG. 8 the
choke 88 is shown on the pin 60 in the open position.
When the choke 88 is positioned on the pin 60, not only does the
pin 60 pass through the choke transverse bore 92, but as the pin 60
intersects the longitudinal bore 90 of the choke 88, it extends
through the opening in one of the chain links 72. With the pin
engaging one of the chain links 72 in the chain cannot be moved in
the bore 90. Thus the size of the chain loop 94 is maintained.
In operation, the size of the loop 94 is selected. Then the pin 60
is passed through the transverse bore 92 and through the chain link
72 opposite the bore 92 within the bore 90. In this manner, the
choke 88 is connected to the locking device 10, and the size of the
loop 94 in the chain 70 extending from the choke 88 is
maintained.
FIG. 10 illustrates one example of use of the locking device 10 to
lock a personal item, such as a camera 96, to a stationary object,
such as a post or pole 98. First, the loop 94 is formed in the
chain 70. The opposite free end of the chain with the cap 78
attached thereto is extended around the post 98 and through the
loop 94. Preferably, the post 98 does not have an exposed upper end
portion which would allow the chain to be easily removed. One
example would be a long pole or light standard where one end is
secured in the ground and the other end is at such a height which
would discourage removal of the chain from the post 98.
The opposite end of the chain 70 with the cap 78 secured thereto is
engaged by the pin 60 when the pin is in the open position, as
shown in FIG. 2. The free end of the pin 60 when in the open
position is passed through one of the links 72 and is also extended
through an eyelet 100 that extends from the side of the camera 96.
The eyelet 100 is commonly used to attach a strap to the camera 96.
Then the pin 60 is moved to the closed position and the lock
element 28 is locked. In this manner, the camera 96 is locked to
the locking device 10 and the chain 70 which is secured to the post
98 is also locked to the locking device 100 to thereby secure the
camera 96 to the post 98.
FIG. 8 illustrates a similar example of use of the locking device
10 to secure a garment, such as a coat 102, to a doorknob 104.
First, the loop 94 is extended over the doorknob 104, and the choke
88 is advanced on the chain 70 to reduce the size of the loop 94 so
that it cannot be removed from the doorknob 104. Then, with the
choke 88 maintained in this position, the pin 60 is passed through
the transverse bore 92 of the choke 88 intersecting one of the
chain links 72 in the portion of the chain 70 that extends through
the choke longitudinal bore 90. The coat 102 is then secured to the
pin 60 by passing the unlocked pin 60 through a hole 106 in the
collar of the coat 102. The pin 60 is then inserted, as above
described, in the pin receiving recess 22 to lock the pin 60 in the
closed position. Thus, the chain 70 and the coat 102 are locked to
the locking device 10.
FIGS. 12 and 13 are similar examples of use of the locking device
10 to secure, as shown in FIG. 12, a telephone 108 in a position to
prevent its use and, as shown in FIG. 13, to secure a toolbox 110
from being opened. In order to prevent use of the telephone 108,
the chain 70 is wrapped around the telephone cradle 112 and the
telephone 108 thereon. As with the arrangement shown in FIG. 11,
the choke 88 is advanced on the chain 70 to close the loop 94
tightly around the telephone 108 and the cradle 112. As above
described, the choke 88 is secured to the locking device 10 in the
locked position. This prevents the telephone 108 from being removed
from the cradle 112 and being used.
In the example shown in FIG. 13, neither the chain 70 nor the choke
88 are used and are contained in the storage container 66 while the
locking device 10 is used to secure the latch 114 in a closed
position. This is accomplished by positioning the latch 114 over
the eyelet 116 and then extending the locking pin 60 through the
eyelet 116 and into the closed position, as above described, on the
locking device 10.
FIG. 14 illustrates another example of the use of locking device 10
to secure a handbag 118 to a stationary member 120, such as a post
or the arm of a chair. In this application, the loop 94 is formed
in the chain 70 and extended around the stationary member 120 as
above described with regard to securing the camera 96 to the post
98 as shown in FIG. 10. The locking device 10 in the unlocked
position is secured to the handbag 118 by extending the pin 60
through the opening in the zipper closure 122.
As shown in FIG. 14, the zipper 124 is, of course, first closed to
seal the contents within the handbag 118. With the zipper 124
closed, the pin 60 is extended through the opening in the zipper
closure 122 and also extended through a loop of material 126 which
forms part of the strip 128 that is connected to the handbag 118.
Pin 60 is then moved into the pin receiving recess 22 and the
locking element 28 is locked to retain the pin 60 in the closed
position.
With the above arrangement not only is the handbag 118 secured to
the stationary object 120, but the handbag is also locked in a
closed position. Of course, if there should be other satisfactory
means of preventing the handbag or any similar object from being
opened, it would not be necessary to lock it using the locking
device 10. In this instance, the locking device 10 would be used to
secure the handbag 118 to the stationary object 120 to prevent
theft or unauthorized removal of the handbag 118 from the
stationary object 120.
It should be understood that the locking device 10 of the present
invention can be utilized to secure any number of small articles,
such as those described above, or others which are too numerous to
mention. The above examples are only representative of a few of the
many applications of locking device 10 in accordance with the
present invention.
According to the provisions of the patent statutes, we have
explained the principle, preferred construction and mode of
operation of our invention and have now illustrated and described
what we now consider to represent its best embodiment. However, it
should be understood that, within the scope of the appended claims,
the invention may be practiced otherwise than as specifically
illustrated and described.
